The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0060] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0061] See also Figures 1 to 4 , Figures 13 to 16The electronic atomization device 10 provided by an embodiment of the present invention includes a housing 100, a battery assembly 200 and an atomizer 300, wherein the atomizer 300 includes a shell assembly 310, a base assembly 360 and an atomizer assembly 350, wherein the shell assembly 310, the base assembly 360 and the atomizer assembly 350 can form an atomization mechanism 301. The battery assembly 200 is used to power the atomizer assembly 350, and the atomizer assembly 350 converts electrical energy into heat energy, thereby atomizing a liquid represented by an aerosol-generating matrix to form smoke for the user to inhale.

[0062] See also Figures 3 to 6 In some embodiments, the housing 100 is generally a cylindrical structure with a certain length, and a receiving chamber 101 is provided in the housing 100. The receiving chamber 101 is closed in the circumference and has non-enclosed openings at both ends. The atomizer 300 can be loaded into the receiving chamber 101 from the upper opening of the receiving chamber 101, and the battery assembly 200 can be loaded into the receiving chamber 101 from the lower opening of the receiving chamber 101, so that the atomizer 300 is located above the battery assembly 200.

[0063] See also Figures 3 to 12 In some embodiments, the battery assembly 200 can be slidably disposed in the accommodating cavity 101, that is, the battery assembly 200 is slidably connected to the housing 100. For example, a slide groove 211 is provided on the surface of the battery assembly 200, and the slide groove 211 extends along the sliding direction of the battery assembly 200. A boss 110 is provided on the inner surface of the housing 100, and the boss 110 protrudes from the inner surface of the housing 100 by a set length. The boss 110 and the slide groove 211 are slidably matched, and the battery assembly 200 and the housing 100 are slidably connected through the cooperation between the boss 110 and the slide groove 211. The slide groove 211 has a stop end 211b and a limit end 211a that are relatively arranged, and the stop end 211b is arranged closer to the atomizer 300 than the limit end 211a. See. Fig.12 In the process of the battery assembly 200 sliding upward relative to the housing 100, when the protrusion 110 abuts against the limiting end 211a of the slide groove 211 away from the atomizer 300, the battery assembly 200 stops sliding upward. At this time, the bottom surface 214 of the battery assembly 200 and the bottom surface 130 of the housing 100 can be flush with each other; see Fig.11When the boss 110 abuts against the stopper end 211b of the slide groove 211 disposed near the atomizer 300, the battery assembly 200 stops sliding downward. At this time, one end of the battery assembly 200 away from the atomizer 300 is exposed to the accommodating cavity 101, so that the bottom surface 214 of the battery assembly 200 and the bottom surface 130 of the housing 100 are spaced apart from each other. Therefore, the slide groove 211 can limit the limit travel of the battery assembly 200 sliding up and down. In other embodiments, for example, the boss 110 can be disposed on the battery assembly 200, and the slide groove 211 is provided on the inner surface of the housing 100. For another example, the boss 110 is disposed on the battery assembly 200 and has a certain elasticity, and the slide groove 211 can be replaced by two card slots disposed on the inner surface of the housing 100. Through the cooperation between the boss 110 and the two card slots, the limit travel of the battery assembly 200 sliding in different directions is limited.

[0064] The battery assembly 200 includes a main body 210, a boss 220, an electrode column 230 and an air pressure sensor 215. The cross-sectional dimension of the main body 210 is larger than that of the boss 220. The slide groove 211 is arranged on the side of the main body 210. An end surface of the main body 210 forms a mounting surface 212, the boss 220 is arranged on the mounting surface 212, and the boss 220 protrudes from the mounting surface 212 by a set length. An end surface of the boss 220 forms a limiting surface 221, and the limiting surface 221 is arranged facing away from the mounting surface 212. The electrode column 230 is arranged on the limiting surface 221, and the electrode column 230 protrudes from the limiting surface 221 by a set length. The electrode column 230 includes a first electrode 231, a second electrode 232 and a sensing electrode 233. The polarities of the first electrode 231 and the second electrode 232 are opposite. For example, the first electrode 231 is a positive electrode and the second electrode 232 is a negative electrode. The number of the first electrode 231 as the positive electrode can be one, the number of the second electrodes 232 as the negative electrode can be multiple, and the number of the sensing electrodes 233 can be equal to the number of the second electrodes 232.

[0065] The limiting surface 221 of the boss portion 220 is recessed to form a sensing airway 222, which can extend into the main body 210 in the vertical direction. The air pressure sensor 215 can be arranged in the main body 210, and the air pressure sensor 215 is used to sense the negative pressure in the sensing airway 222. When the user inhales, the gas in the sensing airway 222 is sucked away to form a negative pressure. The air pressure sensor 215 senses the negative pressure information, so that the battery assembly 200 supplies power to the atomization assembly 350, and the atomization assembly 350 atomizes the liquid to form smoke, so that the user can inhale in time. The battery assembly 200 may also include a button 213, which is arranged on the main body 210, and the button 213 is used to control the opening of the battery assembly 200.

[0066] See also Figures 13 to 18In some embodiments, the housing assembly 310 is connected to the base assembly 360, such as by snap connection, etc. The housing assembly 310 includes a mounting shell 320, a liquid storage cylinder 340 and a sealing member 330. The mounting shell 320 is snap-connected to the housing 100 to realize the snap-connected relationship between the entire atomizer 300 and the housing 100, that is, the detachable connection relationship. For example, a snap-fitting hole 120 is formed in a depression on the inner surface of the housing 100, and a mounting hole 321 is provided on the mounting shell 320. An elastic clamping column 322 is provided on the side wall of the mounting hole 321, that is, one end of the elastic clamping column 322 is fixed on the side wall of the mounting hole 321, and the other end of the elastic clamping column 322 is a free end. Since the elastic clamping column 322 has a certain elasticity, the elastic clamping column 322 can swing in the space defined by the mounting hole 321. When the atomizer 300 is snap-connected to the housing 100, the free end of the elastic clamping column 322 cooperates with the snap-fitting hole 120. The mounting shell 320 has a nozzle end surface 324 , and a nozzle hole 323 is formed on the nozzle end surface 324 . The smoke generated by atomization of the atomization assembly 350 is inhaled by the user through the nozzle hole 323 .

[0067] The liquid storage cylinder 340 is accommodated in the cavity surrounded by the mounting shell 320, and the cavity of the liquid storage cylinder 340 can be used to store liquid. When a liquid partition plate 342 is provided in the cavity of the liquid storage cylinder 340, the liquid partition plate 342 divides the cavity of the liquid storage cylinder 340 into at least two different and independent liquid storage cavities 341. When only one liquid partition plate 342 is provided, the liquid partition plate 342 divides the cavity of the liquid storage cylinder 340 into two independent liquid storage cavities 341. The sealing member 330 is pressed between the mounting shell 320 and the liquid storage cylinder 340 and is used to seal the liquid storage cavity 341 to prevent liquid from leaking from the liquid storage cavity 341. The sealing member 330 is also provided with a connecting hole 331, and the liquid storage cavity 341 is connected with the connecting hole 331. The liquid storage cylinder 340 is also provided with a positioning rod 343, and the positioning hole is inserted into the hole opened on the base assembly 360. By providing the positioning rod 343, the installation efficiency and accuracy of the liquid storage cylinder 340 can be improved.

[0068] The atomizer assembly 350 is disposed between the housing assembly 310 and the base assembly 360. The number of the atomizer assemblies 350 is also at least two. The number of the atomizer assemblies 350 can be equal to the number of the liquid storage chambers 341. The two form a one-to-one correspondence, so that each atomizer assembly 350 supplies liquid through the corresponding liquid storage chamber 341, that is, each atomizer assembly 350 supplies liquid through different liquid storage chambers 341. The atomizer assembly 350 is provided with a smoke channel 302, and the smoke channel 302 is used for smoke circulation. All the smoke channels 302 are connected to the suction nozzle hole 323 on the mounting shell 320, that is, the smoke in all the smoke channels 302 is sucked by the user through the suction nozzle hole 323.

[0069] The atomizer assembly 350 includes a mounting tube 351 and an atomizer core 352. The tube cavity 302a of the mounting tube 351 forms the smoke channel 302 of the atomizer assembly 350. When the mounting tube 351 is inserted into the communication hole 331 of the sealing member 330, the smoke channel 302 can be connected to the nozzle hole 323 through the communication hole 331. The mounting tube 351 is provided with a liquid inlet hole 351a, which is connected to the tube cavity 302a. The atomizing core 352 includes a base 352a and a heating element 352b. A through hole 303 connected to the smoke channel 302 is provided in the base 352a, so that the base 352a is roughly a hollow cylindrical tube structure. The heating element 352b is arranged on the inner wall of the through hole 303. The heating element 352b is connected to the electrode contact 365 on the base assembly 360, and the electrode contact 365 can be electrically connected to the electrode column 230 on the battery assembly 200, so that the battery assembly 200 supplies power to the heating element 352b through the electrode column 230 and the electrode contact 365, and the heating element 352b converts electrical energy into thermal energy of the atomized liquid. According to the actual needs, the heating element 352b can be a spatial spiral structure or a membrane structure.

[0070] The substrate 352a can be made of porous ceramic material so that the substrate 352a has a certain porosity, thereby being able to form a capillary force for liquid absorption. The substrate 352a is arranged in the tube cavity 302a of the mounting tube 351 and corresponds to the liquid inlet hole 351a. When the liquid in the liquid storage cavity 341 contacts the surface of the substrate 352a through the liquid inlet hole 351a, under the action of capillary force, the liquid on the surface of the substrate 352a will further penetrate into the interior of the substrate 352a and finally reach the inner wall of the through hole 303, so that the heating element 352b can be atomized.

[0071] The housing assembly 310 and the base assembly 360 are both provided with an air inlet 325, and the air inlet 325 is connected to the outside and all the smoke passages 302. The base assembly 360 includes a silicone seat 361, and the silicone seat 361 is made of silicone material, and the silicone seat 361 can have a certain flexibility. The end of the base assembly 360 has a connecting end face 364, and the connecting end face 364 includes a part of the surface located on the silicone seat 361, and the connecting end face 364 is arranged opposite to the suction nozzle end face 324. In other words, the connecting end face 364 and the suction nozzle end face 324 are oriented in opposite directions. The silicone seat 361 includes a flange 363, and the part of the connecting end face 364 located on the silicone seat 361 is recessed to form an insertion hole 362, and the flange 363 is arranged on the inner wall of the insertion hole 362, and the flange 363 protrudes from the inner wall of the insertion hole 362 by a set length. The base assembly 360 further includes a limiting block 366 , which is located in the insertion hole 362 .

[0072] The entire atomizer 300 is detachably connected to the housing 100 at both the upright position 11 and the inverted position 12. Figure 3 and Figure 5 When the atomizer 300 is in the upright position 11, the nozzle end face 324 is facing upward and facing away from the battery assembly 200, and the connection end face 364 is facing downward and facing the battery assembly 200. The battery assembly 200 is inserted into the insertion hole 362, and the electrode column 230 on the battery assembly 200 and the electrode contact 365 on the base assembly 360 are electrically connected by abutting each other. At this time, the atomizer 300 is in working or standby state, and the user can inhale the smoke generated by the atomizer 300. When the battery assembly 200 is matched with the insertion hole 362, the limiting surface 221 on the boss part 220 abuts against the limiting block 366 located in the insertion hole 362, and the flange 363 is clamped on the side surface 223 of the boss part 220 due to compression (the side surface 223 is connected to the limiting surface 221). In short, the flange 363 clamps the boss part 220. This setting can play the following three roles: First, the battery assembly 200 can be positioned through the abutment between the limiting surface 221 and the limiting block 366, so that the electrode column 230 and the electrode contact 365 are just in abutment state, preventing damage to the electrode column 230 and the electrode contact 365 caused by the large abutting pressure caused by inaccurate positioning; at the same time, the silicone seat 361 has a certain flexibility and will not cause wear to the electrode column 230 or elastic fatigue of the electrode column 230. Second, the limiting effect of the limiting block 366 also prevents the connection end surface 364 of the silicone seat 361 from contacting the mounting surface 212 of the main body 210 and makes them spaced apart. Third, when the limiting surface 221 contacts the limiting block 366, the flange 363 is squeezed by the boss portion 220 and shrinks, so that the flange 363 clamps the boss portion 220 and forms a sealing effect on the insertion hole 362, that is, the boss portion 220 seals a part of the insertion hole 362 to form a flow cavity 362a, and the flow cavity 362a is connected to the sensing airway 222 and the air inlet 325 at the same time. At this time, the flow cavity 362a is also connected to all the smoke channels 302. Therefore, when the user inhales, the gas flowing in from the air inlet 325 will carry the gas in the circulation cavity 362a and the sensing airway 222 through the smoke channel 302 and be inhaled by the user, so that there is a certain negative pressure in the circulation cavity 362a. After the air pressure sensor 215 accurately senses the negative pressure, it can control the battery assembly 200 to power all the atomization assemblies 350 so that all the atomization assemblies 350 can atomize the liquid at the same time.

[0073] When the atomizer 300 is in the upright position 11, the boss 110 on the shell 100 just abuts against the stop end 211b of the slide groove 211 close to the atomizer 300, so that the end of the battery assembly 200 away from the atomizer 300 is exposed in the accommodating chamber 101. At this time, the user can apply an upward thrust to the portion of the battery assembly 200 exposed outside the accommodating chamber 101 so as to push the battery assembly 200 to slide upward. Since the limiting surface 221 of the boss portion 220 applies an upward thrust to the limiting block 366, under the action of the thrust, the elastic clamping column 322 on the atomizer 300 will be disengaged from the engagement with the clamping hole 120 of the shell 100, thereby releasing the connection between the atomizer 300 and the shell 100, which makes it easy to take the atomizer 300 out of the accommodating chamber 101. During the upward sliding of the battery assembly 200, the battery assembly 200 will push the atomizer 300 to slide upward as well. When the boss 110 on the housing 100 just contacts the limit end 211a of the slide groove 211 away from the atomizer 300, the upward sliding stroke of the battery assembly 200 reaches the limit, and the battery assembly 200 stops sliding. At this time, the battery assembly 200 has pushed most of the atomizer 300 out of the accommodating chamber 101, so that the user can directly hold the exposed part of the atomizer 300 to take it away. Of course, for the convenience of suction, when the atomizer 300 is in the normal position 11, the nozzle end face 324 of the mounting shell 320 can be located outside the accommodating chamber 101, and the nozzle end face 324 is spaced a certain distance from the end surface of the housing 100. In short, a part of the atomizer 300 is exposed outside the accommodating chamber 101.

[0074] See also Figure 4 When the atomizer 300 is in a standby state and is not in use, the atomizer 300 can also be connected to the housing 100. At this time, the atomizer 300 is in the inverted position 12. In the inverted position 12, the nozzle end face 324 is facing downward and facing the battery assembly 200, and the connecting end face 364 is facing upward and facing away from the battery assembly 200. The connecting end face 364 is flush with the end surface of the housing 100, or the connecting end face 364 is spaced apart from the end surface of the housing 100 and is located in the accommodating cavity 101. In this way, the entire atomizer 300 does not have any part exposed outside the accommodating cavity 101, thereby minimizing the space occupied by the entire electronic atomization device 10 during carrying and storage. In layman's terms, when the atomizer 300 is connected to the housing 100 in an upright state (working state), the atomizer 300 is in an upright position 11 ; when the atomizer 300 is connected to the housing 100 in an inverted state (resting state), the atomizer 300 is in an inverted position 12 .

[0075] When the atomizer 300 is in the inverted position 12, the nozzle end face 324 is located in the accommodating cavity 101. Obviously, the opening 323b of the nozzle hole 323 on the nozzle end face 324 is also located in the accommodating cavity, that is, the shell 100 forms a protective effect on the nozzle hole 323, and effectively prevents impurities such as external dust or droplets from invading the interior of the atomizer 300 through the nozzle hole 323 to cause pollution. When the atomizer 300 is used again, the user can avoid inhaling the above-mentioned impurities from the nozzle hole 323 to cause harm to human health, thereby improving the hygiene and safety of the entire electronic atomization device 10 during use. At the same time, the boss portion 220 of the battery assembly 200 is accommodated in the suction nozzle hole 323, and the suction nozzle end face 324 of the mounting shell 320 abuts against the mounting surface 212 of the main body 210, so as to limit the battery assembly 200, so that the electrode column 230 does not contact the bottom wall 323a of the suction nozzle hole 323, that is, the end of the electrode column 230 maintains a set distance with the bottom wall 323a of the suction nozzle hole 323, so as to prevent the electrode column 230 from being damaged due to the collision between the electrode column 230 and the bottom wall 323a of the suction nozzle hole 323. In addition, through the abutment of the suction nozzle end face 324 and the mounting surface 212, the opening 323b of the suction nozzle hole 323 can be blocked, so that the battery assembly 200 further protects the suction nozzle hole 323, and impurities such as external dust or droplets will be more difficult to invade from the suction nozzle hole 323. In other embodiments, for example, the opening 323b of the nozzle hole 323 on the nozzle end surface 324 may be located outside the accommodating cavity 101, but the main body 210 or the boss portion 220 of the battery assembly 200 may block the nozzle hole 323, which can also prevent the above-mentioned impurities from entering the nozzle hole 323. For another example, when the nozzle end surface 324 is located in the accommodating cavity 101, the main body 210 or the boss portion 220 of the battery assembly 200 blocks the nozzle hole 323, and the nozzle hole 323 is protected by both the battery assembly 200 and the housing 100, making it more difficult for external impurities to enter from the nozzle hole 323.

[0076] When the atomizer 300 is in the inverted position 12, similar to when the atomizer 300 is in the upright position 11, the protrusion 110 on the housing 100 just abuts against the stop end 211b of the slide groove 211 close to the atomizer 300, so that the end of the battery assembly 200 away from the atomizer 300 is exposed from the accommodating cavity 101. When the user applies an upward thrust to the portion of the battery assembly 200 exposed outside the accommodating chamber 101, the mounting surface 212 of the main body 210 applies an upward thrust to the nozzle end surface 324 of the mounting shell 320, so that the elastic clamping column 322 disengages from the engagement with the snap-in hole 120, thereby releasing the connection between the atomizer 300 and the shell 100. When the upward sliding stroke of the battery assembly 200 reaches the limit, the battery assembly 200 stops sliding, and the battery assembly 200 has pushed most of the atomizer 300 out of the accommodating chamber 101, which is also convenient for the user to directly grasp the exposed portion of the atomizer 300 to take it away.

[0077] During the use of the electronic atomization device 10, when it is necessary to inhale, the atomizer 300 is placed in the upright position 11. When the inhalation is completed and there is no inhalation for a considerable period of time, the battery assembly 200 can be pushed upward to disengage the elastic clamping column 322 from the card hole 120 to release the connection between the atomizer 300 and the housing 100, and then the atomizer 300 in the upright position 11 is pushed out of the accommodating chamber 101 by the battery assembly 200. Then, the user takes out the atomizer 300 from the accommodating chamber 101 and turns it from the upright state to the inverted state, and then reconnects the atomizer 300 in the inverted state to the housing 100, that is, the elastic clamping column 322 re-matches with the card hole 120, thereby preventing impurities from entering the suction nozzle hole 323. When it is necessary to inhale again, the battery assembly 200 is pushed upwards to disengage the elastic clamping column 322 from the clamping hole 120 to release the connection between the atomizer 300 and the housing 100, so that the atomizer 300 in the inverted position 12 is pushed out of the accommodating chamber 101 by the battery assembly 200. Then, the user takes out the atomizer 300 from the accommodating chamber 101 and turns it from the inverted state to the upright state, and then reconnects the atomizer 300 in the upright state to the housing to inhale again.

[0078] Therefore, the battery assembly 200 is slidably connected to the housing 100, and the atomizer 300 can be quickly installed and disassembled simply by pushing the battery assembly 200 to slide in the accommodating cavity 101, without the need for the design of other complex parts and structures, thereby ensuring the simplification of the structure of the entire electronic atomization device 10 and making the electronic atomization device 10 more convenient to use.

[0079] When the liquid storage cylinder 340 forms two independent liquid storage chambers 341 by setting a liquid partition plate 342, each liquid storage chamber 341 corresponds to an atomizer assembly 350. When the user inhales, the air pressure sensor 215 can sense the existence of negative pressure through the sensing airway 222 and the circulation chamber 362a, so that the battery assembly 200 supplies power to the two atomizer assemblies 350 at the same time, and the two atomizer assemblies 350 simultaneously atomize the liquid to form smoke. Compared with one atomizer assembly 350, the amount of smoke generated by the two atomizer assemblies 350 working at the same time increases, thereby increasing the concentration of the smoke. At the same time, liquids of different flavors can be contained in the two liquid storage chambers 341, and smoke of different flavors is mixed in the suction nozzle hole 323 to be inhaled by the user, so that the taste of the electronic atomization device 10 can be enriched and its taste diversity can be improved. In other embodiments, the number of both the liquid storage chamber 341 and the atomizer assembly 350 can be one or more than two. When a smaller smoke concentration is required, or only one flavor is required, a single atomizer 350 can be turned on.

[0080] When there are two atomizer assemblies 350, there is one first electrode 231 as the positive electrode, which is centrally arranged on the boss portion 220. The first electrode 231 as the positive electrode is electrically connected to all atomizer assemblies 350 at the same time, that is, all atomizer assemblies 350 share one first electrode 231. There are two second electrodes 232 as the negative electrode, which are symmetrically distributed on both sides of the first electrode 231, and are electrically connected to different atomizer assemblies 350 respectively. There are also two sensing electrodes 233, which are located at the edge and are also symmetrically arranged relative to the first electrode 231. By setting the sensing electrodes 233, the taste information of the smoke generated by different atomizer assemblies 350 can be identified.

[0081] See also Figures 19 to 23In some embodiments, the atomizer 300 further includes a liquid absorbing assembly 370, which includes a push member 371, a liquid absorbing member 372, an elastic member 373 and a sealing member 375. The liquid absorbing member 372 can be made of liquid absorbing cotton, so that the liquid absorbing member 372 has a good liquid absorbing function. The push member 371 is recessed on the surface of the bottom wall 323a of the suction nozzle hole 323 to form a sink 371a. The liquid absorbing member 372 is embedded in the push member 371 by cooperating with the sink 371a, so that the liquid absorbing member 372 is closer to the bottom wall 323a of the suction nozzle hole 323 relative to the push member 371. At the same time, the liquid absorbing member 372 can also be arranged close to the side wall of the suction nozzle hole 323, so that the liquid absorbing member 372 can quickly absorb the condensed liquid on the side wall of the suction nozzle hole 323. The push member 371 may also be provided with an air outlet 371b, which is connected to the outside and the nozzle hole 323. The push member 371 may be slidably disposed in the nozzle hole 323. When the push member 371 slides, the liquid absorbing member 372 can follow the push member 371 to slide in the nozzle hole 323, so that the liquid absorbing member 372 can absorb the condensed liquid on the side wall of the nozzle hole 323 to the maximum extent. Since the condensed liquid is absorbed in the liquid absorbing member 372, and the condensed liquid absorbed in the liquid absorbing member 372 cannot penetrate the push member 371, the user will not be able to inhale the condensed liquid in the nozzle hole 323 during the suction process, thereby improving the hygienic safety of the entire atomizer 300 when in use.

[0082] A limiting protrusion 376 is provided on the side wall of the suction nozzle hole 323, and the limiting protrusion 376 is provided close to the suction nozzle end face 324. For example, the surface of the limiting protrusion 376 can be flush with the nozzle end face 324. In the case that the pushing member 371 slides close to the nozzle end face 324, when the pushing member 371 abuts against the limiting protrusion 376, the pushing member 371 stops sliding, that is, the limiting protrusion 376 limits the maximum sliding stroke of the pushing member 371 close to the nozzle end face 324, and can also prevent the entire liquid suction assembly 370 from falling from the suction nozzle hole 323.

[0083] The bottom wall of the nozzle hole 323 is provided with a convex strip 374. The elastic member 373 may be a spring. The spring is sleeved on the convex strip 374. The convex strip 374 guides and positions the spring. The lower end of the spring abuts against the bottom wall of the nozzle hole 323. The upper end of the spring abuts against the push member 371. The sealing member 375 may be a sealing ring. The sealing ring is sleeved on the push member 371 and abuts between the push member 371 and the side wall of the nozzle hole 323. The sealing member 375 can prevent condensate on the side wall from flowing out of the nozzle hole 323.

[0084] For the atomizer 300 including the liquid suction component 370, when the atomizer 300 is in the upright position 11, the smoke generated by the atomizer component 350 can be sucked by the user through the suction nozzle hole 323 and the air outlet 371b. At the same time, due to the absorption of the condensed liquid by the liquid suction component 371, the condensed liquid in the suction nozzle hole 323 will not be sucked into the user's mouth, further improving the safety and hygiene of the atomizer 300. Of course, on the basis that the push member 371 has good air permeability, the air outlet 371b can be cancelled. When the atomizer 300 is in the inverted position 12, the electrode column 230 can be accommodated in the air outlet 371b of the push member 371. At the same time, the limiting surface 221 of the boss portion 220 is pressed against the surface of the push member 371, and the push member 371 moves toward the bottom wall of the suction nozzle hole 323, and the elastic member 373 is gradually compressed, and the liquid absorbing member 372 is driven by the push member 371 to contact the bottom wall of the suction nozzle hole 323. At this time, the condensate on the bottom wall 323a and the side wall of the suction nozzle hole 323 will be completely absorbed by the liquid absorbing member 372, preventing the condensate from contacting the battery assembly 200 and corroding it, thereby improving the life of the battery assembly 200 and the electronic atomization device 10. When the atomizer 300 is in the inverted position 12, the limiting surface 221 of the boss portion 220 is in contact with the push member 371, so that the mounting surface 212 of the main body 210 does not contact the suction nozzle end surface 324, and the two are kept at a certain distance and spaced from each other. When the atomizer 300 needs to be pushed upward out of the accommodating cavity 101 , the battery assembly 200 can be pushed to apply an upward force to the pushing member 371 through the limiting surface 221 , thereby releasing the connection between the atomizer 300 and the housing 100 so that the atomizer 300 can be pushed out by the battery assembly 200 .
